Definitions

  • the present invention is in the field of protective and ballistic proof materials, more specifically, compound protective or armored transparent structures.
  • An armored/ballistic glass pane may consist of a single armored layer or a combination of several glass layers interleaved with bullet proof layers, for example plastic layers. Examples of protective or armored glass are disclosed in US Patent Application 2004/0209053.
  • a common issue with such armored glass is delamination between the glass and plastic layers that are typically used. Delamination results in decreased protection from bullets or other ballistic threats. In such case, the armored glass may need to be replaced.
  • An average life of ballistic glass that comprises a combination of a glass layer attached to a polycarbonate layer is about two years. The solution as provided in the instant invention can considerably prolong the life of the armored glass.
  • a transparent armored composite structure comprising: an external layer comprising at least one glass and/or transparent plastic layer arranged to face toward an expected impact; a rear layer comprising a plastic layer; and a spacing mechanism intermediate the external layer and the rear layer defining a space therebetween, wherein rear layer comprises a moisture proof coating.
  • moisture proof material denotes any material that hinders the passage of moisture.
  • the moisture proof material is primarily intended to reduce the passage of moisture into the space provided by the spacing material ; however, in cases where the rear layer further comprises a glass layer adjacent its plastic layer, the moisture proof material may be located intermediate the plastic and glass layers and reduce or slow the incidence of delamination between those layers.
  • the at least one glass and/or transparent plastic layer of the external layer is ceramic glass.
  • rear layer further comprises at least one glass layer.
  • the coating comprises Silicon dioxide, in particular wherein the Silicon dioxide is the predominant component of the coating.
  • the external layer comprises a transparent plastic layer sandwiched by a pair of glass layers.
  • the transparent plastic layer is an adhesive plastic layer.
  • a method of producing a transparent armored composite structure comprising the steps of: (a) providing an external layer, comprising at least one glass and/or transparent plastic layer arranged to face toward an expected impact; (b) providing a rear layer, comprising a plastic layer; and (c) disposing the external layer and plastic layer spaced apart from each other via a spacing mechanism defining a space between the external and rear layers, wherein prior to step (c), the method comprises applying a moisture proof coating to the rear layer.
  • the method comprises arranging the glass and plastic layers so that the coating is intermediate those layers.
  • a transparent armored composite structure comprising: an external layer comprising at least one glass and/or transparent plastic layer arranged to face toward an expected impact; a rear layer comprising a plastic layer and a glass layer; and a spacing mechanism intermediate the external layer and the rear layer defining a space therebetween.
  • rear layer does not comprise coating.
  • a method of producing a transparent armored composite structure comprising the steps of: (a) providing an external layer, comprising at least one glass and/or transparent plastic layer arranged to face toward an expected impact; (b) providing a rear layer, comprising a plastic layer and glass layer adjacent one another ; and (c) disposing the external layer and rear layer spaced apart from each other via a spacing mechanism defining a space between the external and rear layers,
  • Fig. 1 is a sectional view of an embodiment of an armored composite unit in accordance with the present invention
  • Fig. 2 is a sectional view of another embodiment of the armored composite unit in accordance with the present invention.
  • Fig. 1 shows an embodiment of a transparent armored composite structure of the invention comprising a protective transparent unit 10.
  • the protective transparent unit 10 comprises two spaced apart layers, an external layer 12 and a rear layer 14.
  • External layer 12 comprises at least one transparent layer including one or more glass and/or plastic layers and typically has anti-ballistic properties.
  • Rear layer 14 is typically disposed parallel to protective unit 12.
  • rear layer 14 comprises one layer, a plastic layer 24, e.g. polycarbonate or another transparent plastic layer which is suitable for preventing spalling, e.g. preventing shattering glass from entering the inner space of a vehicle, for example.
  • a spacing mechanism comprising one or more spacing elements 16, holds external layer 12 and rear layer 14 spaced apart defining an air space 18 therebetween.
  • the spacing element(s) 16 are typically in the shape of a frame and according to some embodiments comprise a moisture absorbing material or/and a moisture barrier, for example, hygroscopic rubber.
  • an adhesive plastic 21 such as polyurethane, is applied over spacing elements 16 to attach external layer 12 to rear layer 14.
  • External layer 12 is an impact resistant layer for resisting projectiles, such as bullets.
  • external layer 12 is positioned facing the expected projectile impact, represented by arrow 19.
  • External layer 12 may be laminated or consist of one glass sheet.
  • a laminated unit typically comprises two or more glass layers 20 interleaved with one or more plastic adhesive sheets 22, for example, as shown in Fig. 1 , wherein glass layers 20 sandwich plastic sheets 22.
  • Plastic sheets 22 commonly comprise PVB (Polyvinyl butyral) or polyurethane sheets adhered to glass layers 20.
  • plastic layer 24 of rear layer 14 is coated with a film or coating 25 to help prevent moisture and/or debris from entering and accumulating between the layers, which may damage the optical transparency of the armored glass structure for example, by causing clouding.
  • Coating 25 of plastic layer 24 is typically a transparent moisture proof or impermeable material.
  • the material of coating 25 can be, for example, a gel applied to the plastic layer.
  • the layer can be applied in the form of a spray, aerosol or any other form, covering plastic layer 24.
  • Coating 25 can comprise, for example, a thin layer of Silicon dioxide, such as liquid glass, manufactured by "Nanopool” (76 Zum Felsacker Str., Schwalbach, Germany 66773).
  • FIG. 2 shows another embodiment of an armored transparent composite unit wherein rear layer 14 comprises two layers, plastic layer 24 and a glass/plastic composite or glass layer 26.
  • Plastic layer 24 commonly comprises polycarbonate, which is typically the outward facing layer thereof, and is adhered to glass layer 26.
  • PVB Polyvinyl butyral
  • polyurethane are examples of suitable adhesives for such matter. This embodiment is particularly useful when the protective transparent unit 10 is not flat (i.e. curved, convex, concave or any other non-flat shape; for example in the case of front and rear vehicle windshields).
  • Glass layer 26, attached to plastic layer 24 contributes to the support of the curved shape of the plastic layer which generally conforms to the form of the glass layer to which it is adhered.
  • Coating 25 is applied onto plastic layer 24 and arranged so that the coating abuts glass layer 26 to hinder such delamination.
  • coating 25 can be applied to glass layer 26.
  • coating 25 may be applied onto additional plastic and/or glass layers in order to provide additional delamination hindrance to protective transparent unit 10.
